termites on boats

Dry woods, otoh, don't need to live in the ground. They spread by wing and can infest any wood structure, with no need to go underground.

When subterranean termites infest a home, the colony can already be huge, so they can do serious damage in a short length of time. Dry woods, like you no doubt have, do their damage very slowly. Although the colonies are small, the problem arises when they swarm, re infest other areas, and eventually you end up with many, many small colonies that together do substantial damage.

Boats can be sealed up and treated just like a house. I've seen the typical tents used, but more often the boat is sealed up with duct tape and plastic. I can't imagine there's not exterminators with access to the Vicane gas used in every country. Vicane is what is used in the US, possibly in some countries there's still access to the older, more potent treatment gases.

Another stop gap measure is to spot treat the area. If you look closely above the tell tale pellet piles, there will be very small holes were the termites periodically dump the pellets out of the nest. There are some aerosol treatments you pump into the holes with a needle like applicator. Also, there's a couple of area treatments used to treat the wood surface. It basically just makes the wood poison to the termites. They can be found at do it yourself pest control places, and also eco friendly type sources.

Good luck.
